Clocked at 324MHz, the SH7764 is claimed to yield 583 MIPS (millions of instructions per second) — enough to run feature-rich operating systems such as Linux and Windows CE without sacrificing performance, Renesas says. Such operating systems reduce development time and cost, according to the company.

The SH7764 is based on the superscalar Renesas SH-4A core, which debuted in August of 2004. The core was designed to handle multimedia processing on systems without dedicated DSPs (digital signal processors), Renesas said at the time.

The SH-4A core integrates 32KB each of instruction and data cache, 16Kb of on-chip RAM, and a 108MHz 32/64-bit bus for connections to external SDRAM. The core also integrates a powerful single-/double-precision FPU (floating point unit) with hardware sine/cosine and vector math accelerators.

Renesas says the SH7764 includes a comprehensive array of on-board peripheral interfaces, including:
